It may be cliche these days on Steemit, but this is a fantastic post!
Ever since I heard about PoS and blockchains like Bitshares and Steem I felt they were FAR superior in so many ways, especially the ones that really matter for healthy and sustainable revolution to the world.
I have never heard of Keen but now I am very exited to look into his work as I love being on the cutting edge.
